You have nitrites, so your ammonia is dropping to some degree but I suspect the amount of ammonia right now is too high to be able to detect a drop yet thus a water change is needed. In respect to the ph, you definitely need to keep track of it while cycling. Have you tested your ph with the high range ph test? With the regular ph test, a 'blue' reading can mean your ph is 7.3 or 8.8- you need to check it against the high test for a more accurate reading. There is no need to play around with your ph while fishless cycling unless it starts to crash regularly.
Unless you plan on keeping a difficult/sensitive species of fish, theres no need to alter ph either- most fish are quite adaptable to a range of phs as long as you take the time to properly acclimate them. The only way to truly lower your ph is to cut it with RO water or use only RO- this is another topic altogether. Driftwood/peat moss can also help to lower ph to some degree as well. We dont know what your tanks ph is actually reading right now, especially if there is an excess of ammonia in it (which can bump up the ph too). So, do the wc and check your ph tomorrow using both the high & regular ph tests.
